Lateral tautness 



Is this the same as pulsación?

RE: Lateral tautness (in reply to rombsix

While the argument can be made that a reduction in lateral tauticity can soften Pulsación due to its relationship with liminal stiffness, the broader consensus is only Californians actually believe it.

I'd be more concerned about those black golpeadors. You can't see behind them. For all we know the darned things are spring loaded. It takes a very deft touch to manage a sprung golpe.

If he used that term the way some do, he seems to be under the biased illusion as many are that this is the case.

Classical guitarists rarely if ever examine neck angle and bridge height. Without that info we don't understand the ACTION, neither over the fingerboard, nor on the right hand. If we do golpe we can talk about the percussive response of the top, and sorry but that has nothing to do with ease of playing which is 100% ACTION. Lower it and it gets easy but loses volume/projection aka response. Raise it, it gets stiffer but louder, more responsive dynamically. It is a balance to achieve. Finally humidity can affect the response so the guitar once easy to play loses all its bright tone and makes you want to play harder, and the guitar feels "dead". It dries out and suddenly she is back to life. But the top is giving the equalization not ease or difficulty of playing notes with your fingers.

Lateral tautness?

I don’t think that word means what you think it means.

I mean, pulcasion is not the first thing that comes to mind when one mentions lateral tautness…

You gulped my classical,

Inconceivable!

How about liminal stiffness?

RE: Lateral tautness (in reply to rombsix

I lost patience at 5 minutes in. Whenever classical guitar oriented fellows start talking about flamenco guitars my tendency is to tune out. They just never get it.

The string height dramatically effects this thing he calls ‘lateral stiffness’ it’s not stiffness in the top itself, it’s stiffness created by string tension created by action height. And the notion that someone selling guitars took that long to notice this phenomenon makes me wonder if it’s because they finally got over the flamenco guitar vs classical guitar schism and decided to play some flamenco guitars with an open mind.

Even though people say the schism is old fashioned it’s still very prevalent.

Every luthier and pro player in Spain is aware of the concept of “pulsaciòn”.
It’s an obvious concept (Anders spoke about it in many occasions) and I really don’t get what’s the issue about it in this foro.

The video doesn’t take into account that a long scale often gives the perception of softer strings under your fingers in spite of the actual higher tension.

Ricardo are you angry when you write action in all caps, or simply frustrated and want to emphasize a point?

But yes, classical guitars are so strange to me because they can have an action that’s anywhere between 8mm and 13mm above the top. With an average off the top gap of 9mm to 12mm - its common to see classicals with that wide of a spread of action. While we who strive to make a low action that’s 7.5 to 8.5 off the top at the saddle are very sensitive to the tightness of the strings. I’m feeling 1mm of action height up or down can make a significant shift in how the guitar feels in terms of string tension.

Adding that when I don’t have the constraint of building the flamenco action, my classical building action is a piece of cake. It’s easy because you can hit a wider target with the saddle height in order to get the action at the 12th fret you’re aiming for. Whereas a flamenco is a tighter tolerance job and takes finer adjustments to get the rasgueado to feel just right.

It’s just a vastly different set up and can see why classical players don’t obsess over it like flamenco players do.

I liked my answer best, followed by HR's, then Echi's observation that a long scale often gives the perception of softer strings...although that one made sense so loses a couple of points.

I left the video when he said a millimetre is a very tiny amount...sheesh....

Interesting.
That is the pretty much the only part which made sense to me, at least when it comes to scale length

Like who cares if a flamenco guitar is 65, 66, 67 or whatever. We play with Capo 99% of the time anyways. It makes it even easier to play if longer scale length and using Capo, it's not that cramped. And mind you, I have small hands. mm is only important vertically (distance between strings is much more important and there the 1 mm counts), not horizontal (I hope this doesn't end in WW4 over mm again lol)

The rest of the video was pretty much using some fancy words to sell a guitar with probably good action and setup, that's all. Letting some classical guitarists play classical pieces on a flamenco guitar and find it easier to play than their usual classical guitar. WOW lol what a surprise. like come on dude.

And it's sold, so good job

RE: Lateral tautness (in reply to Arash

I agree with you. Especially with your observation about the use of a capo.

But he was saying it to marginalize differences in scale length in the service of making a sale. Saying the guitar "plays like butter" was the giveaway. You nailed that one, too.

P.S. guitar making people's noses get a little out of joint when it comes to things like people who are used to the imperial system implying a millimetre is some kind of microscopic unit of measure (but 1/32" isn't? Even though that's a smaller amount?). A difference of a millimetre in neck depth, for instance, makes a huge difference in feel. But, I get you, if he was saying it is a very small amount in relation to the total scale, he's not off, I agree with that, too. It's all relative.

Cool.

I agree with you on the black golpeadors.
Maybe two giant holes beneath them which make the top very loose with nice lateral pulsacion

RE: Lateral tautness (in reply to Arash

I do think scale length can influence how a player will approach an instrument, however. For sure, in electric guitar I'll play a longer scale guitar a little differently when soloing, maybe make different choices in bends, positions, and setting up a lick. But it's more intuitive, not really conscious, it's also a less formalized setting than classical or flamenco playing.

And I've always wondered why it was such a big deal with flamenco, too, because of the capo, but I'm not good enough at flamenco playing for it to make much difference, either way, so I never trusted my judgement on that. I have relatively long fingers, too, so that might play into it, but if I suck at something at 660 I'm probably also going to suck at 650, so I don't blame the instrument, for sure, it's me. I don't find 660 hard to play.

Including or excluding Amalia Ramirez who learned from her dad to adjust the pulsación by checking string height at the 12th fret??

I can't find her video, but explained it here after it appeared.

Emphasize a point obviously, because I am always angry. See I can type this completely infuriated (from searching for Amalia damn video) with no caps whatsoever, easy!

Meanwhile this dude is like hold my beer


Anyways, back to the initial question.
I might have gotten this whole "pulsacion" thing wrong then if one guy says it is lateral top stiffness ,taughtness or whatever, a luthier says it is only action at 12th fret, another something different. I always though it is basically a word for "is the overall feel good and flamenco when you play it or not and can you connect with the instrument or not" or something like that, just like duende is for inspiration and all the other magic happening
Maybe a primitive view.

Each guitar turns out just a bit different in it's entirety than the other. Even exact same brand, same action, same model, same strings, same wood type, same whatever. Probably very small details which on their own are maybe not noticible, add up and once an instrument is built and finished, they show in the final result.

In a way, that is also kind of interesting and makes the whole guitar searching more exciting and surprising.

Does varying string tension affect what is meant by "pulsacion"?

RE: Lateral tautness (in reply to eccullen

In a general sense, it's varying a parameter of a system so it's not unreasonable to expect the system will respond differently to a similar stimulus. And the change in response might not be as predictable as one may hope. Beyond that, I can't answer concerning pulsación because at this point I'm not even sure I know what it means.

At any rate, I'm the guy who just coined the phrase "liminal stiffness" and implied golpeadors could be spring loaded. WTF? I believe we should pass this one on to ....


Cap'n FURIOUS!
